DUMP-WAGON.

Specification of Letters'Patent.

Patented Sept. 26, 1916.

To all whom it may concern Be it known that I, ADAM J. KooB, a'citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Dump-Wagon, of which the following is a specification.

This invention relates to dump wagons especially designed for use in handling sand, dirt, building material and the like, one of the objects of the invention being to provide a wagon of this character utilizing hinged bottom sections having novel means for locking them in raised or supporting posi- 5 tion, said bottom sections being readily released by the driver but being provided with means whereby accidental release of the sections is prevented.

A further object is to provide a wagon of this type the bottom sections of which are adapted to hang freely in such a manner that sand or the like will not accumulate upon any portions thereof and interfere with the proper closing of the sections.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter" described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the in vention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a plan view of the wagon. Fig. 2 is a vertical longitudinal section taken therethrough. Fig. 3 is a vertical transverse section showing the levers in the position assumed thereby when the bottom sections are closed. Fig. 4 is a vertical transverse section through the middle portion of the wagon and showing the bottom sections open.

Referring to the figures by characters of reference 1 and 2 designate the front and rear axles respectively of the wagon, the

same supporting the bolsters 3 and 4 respec tively. Mounted on these bolsters is the vehicle body 5 the side boards 6 of which are connected near their rear ends by an end board 7 and, at a point back of their front ends by an end board 8. The space between the side boards '6 and the endboards 7 and 8 is adapted to be closed by bottom sections 9 hingedly connected to the respective side boards. Each bottom section is preferably mounted as shown in Fig. 4, one leaf 10 of each hinge 11 being extended upwardly along and secured to the outer side of the adjacent board 6 while the other leaf 1?. of each hinge is extended across one edge of the bottom section 9, as shown at 13, and thence across the bottom of said section 9 as shown at 14:- Consequently, when the bottom sections are in closed positions, their side edges are held substantially flush with the outer sides of the boards 6. Then, however, the bottom sections are permitted to swing downwardly to their open positions, the upper or outer edges thereof will move outwardly away from the boards 6 so that no ledges or projections are left upon which sand or other material might accumulate while being dumped from the wagon.

Journaled within the bolsters 3 and 4 are elongated bails 15. The intermediate portion of each bail is longer than the bottom sections 9 and when these sections are in their raised or closed positions, they bear downwardly on the intermediate portions of the bails, the arms 16 at the ends of the bails being at this time substantially vertical so that the weight of the bottom sections and the load supported thereby is transmitted vertically through the arms 16 to the bolsters and axles and there is no danger of the weight shifting the bails 15 laterally out of supporting positions.

The front portions of the bails project forwardly beyond the bottom sections 9 and are pivotally engaged by links 17 which converge upwardly and project through an opening 18 formed between the front ends of the sections 9 and a board 19 which is fixedly connected to the bottom edges of the side boards 6 close to the front ends thereof.

Opposed levers 20 are fulcru-med within the opening 18 and extend close to the board 8, each of these levers being provided with an arm 21 extending upwardly therefrom and pivotally connected to one of the links 17. The levers and arms, as well as links 17 are so proportioned that when said levers are shifted laterally against the side boards 6, they pull through arms 21 and links 17 upon the bails 15 so as thus to raise the bails to positions with their arms 16 vertical. This upward movement of the bails causes their intermediate portions to bear against the bottom sections or closures 9 and to swing said closures upwardly to the positions shown in Figs. 1 and 2. With the bottom closures thus located, the weight supported thereby will be upheld by the bails and said bottom sections can only be lowered by swinging levers 20 so as to shift the bails out of the vertical planes occupied by them. In order to lock the bails against accidental movement whereby the bottom sections might be released, a bracket 22 is mounted on the bottom board 5 above the front end of each of the bails l5 and pivotally mounted in each bracket is a dog 23 having a, downwardly extending finger 24: at its rear end. When each bail 15 is swung upwardly to its active or supporting position, the finger 2% of the adjacent dog is adapted to assume a position. back of thebail so as to prevent return movement of the bail. The dog can be'locked in this positionv by swinging a locking bail 25 over the forward end of the dog, as shown in Figs. 1 and 2. This locking bail is pivoted at its ends in the side boards .6 and is of such length as to extend over both of the dogs and hold them in looking positions.

lVhen it is desired to release the bails 15 to enable the load to be dumped, the driver pushes forwardly on the bail 25 to disengage it from the forward ends of the dogs 23. The fingers 24, acting as weights, will thus swing downwardly and out of the paths of the bails 15. By then slightly 'shiftingthe levers 20 out of their lateral positions, the bails 15 will be moved "from Copies of this patent may be obtained for bails to swing laterally to the positions shown in Fig. .4, thus moving each lever from one side to the other of the vehicle.

body.

Obviously the bottom sections can be re turned totheir closed positions readily by reversing the foregoing operation.

What is claimed is In a. dump wagon, the combination with a body including connected side and end boards, and bottom sections :hingedly connected at their outer sides to the respective side boards, nally under the body and adapted to straddle the respective bottom sections sections are in dumping position, said bails and bottom sections being movable about parallel axes, levers fulcrumed on the body, a link connection between each lever and the intermediate portion of one of the bails, said levers and links constituting means for swinging the bails toward each other to thrust against the bottoms of the bottom sections throughout the lengths of the sections to close the sections, said bails being at dead centers when the bottom sections are closed, thus to support the entire weight of the bottom sections and the load thereon,

and means upon'the body and engaging the bails for holding said bails in load supporting positions.

In testimony as my own, I have hereto affixed my signature in the presence of two witnesses.
